Dial Case Study Overview 1-9

Overview of Tasks

The network devices in this case study are manually conﬁgured using Cisco IOS software.

The automatic Cisco IOS setup script is not used. This setup script usually runs when no startup

conﬁguration is found in NVRAM (for example, when powering up a new router).

Here is the action plan to build the network. For step-by-step conﬁguration tasks, refer to the

device-speciﬁc conﬁguration chapters that follow.

Step 1 Set up async shell services on the Cisco AS5300. See chapter 2 “Cisco AS5300

Conﬁguration.”

— Conﬁguring the Host Name, Password, and Time Stamps

— Conﬁguring Local AAA Security

— Conﬁguring the Fast Ethernet 100BaseT Interface

— Commissioning the T1 Controllers

— Conﬁguring the Serial Channels to Let Modem Calls Come in

— Conﬁguring the Modems and Lines

— Testing Async Shell Connections

Step 2 Set up async PPP services on the Cisco AS5300. See chapter 2 “Cisco AS5300

Conﬁguration.”

— Setting Up IP Address Pools

— Conﬁguring the Group-Async Interface

— Testing Async PPP Connections

Step 3 Set up synchronous PPP services on the Cisco AS5300. See chapter 2 “Cisco AS5300

Conﬁguration.”

— Conﬁguring DDR

— Conﬁguring Deﬁnitions for Remote LAN Sites

— Conﬁguring a Backhaul Routing Protocol

— Conﬁrming the Final Running Conﬁguration

— Saving the Conﬁguration

— Testing Sync PPP Connections to Remote LANs

— Adding More Remote LAN Sites as Needed

Step 4 Conﬁgure the Cisco 1604 to dial into the Cisco AS5300. See chapter 3 “Cisco 1604

Conﬁguration.”

— Conﬁguring the Host Name, Password, and Time Stamps

— Conﬁguring Local AAA Security

— Conﬁguring the Ethernet Interface

— Conﬁguring BRI

— Conﬁguring DDR

— Testing Connections to the Cisco AS5300
